SPECIFICATION formingpart of Letters Patent No. 661,375, dated November6. 1900.

.apuntaron ined April 25,1900.

To (1J/Z whom t may concern,.-

Be it known that l, FRANK MACK, a citizen of the United States, and aresident of the city of New York, borough of Manhattan, in the countyand Stale of New York, have invented new and useful Improvements inHorse-Blinkers, of which the following is a full, clear, and exactdescription.

This invention has for its purpose to provide horse blinkers or blinderswhich may be employed to completely blind a horse, and thereby to stopit.

This specification is the disclosure of one form of the invention, whilethe claims dene the actual scope thereof.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the views.

Figure 1 is a View showing my invention in use. Fig. 2 is an enlargedside elevation with parts broken away. Fig. 3 is a section on the line 33 of Fig. 2, and Fig. 4 is a section on the line 4 4 of Fig. 2.

The device has a body-plate 5, adapted to be fastened tothe bridle bystraps or like devices (3, so as to hold the shade 7 in juxtapositionwith the eye, as shown in Fig. 1. A tube 8 is fastened to the body-plate5 and contains a reciprocally-mounted rod 9. An expansive spiral spring10 encircles this rod and enters the tube 8, the spring serving to nor*-mally throw the rod 9 into the position shown in Figs. 2 and 4. Theupper end of. the rod E) is connected with a cord, chain, or otherflexible structure 11, which passes upward over an idler-pulley 12,mounted at the top of the body-plate 5, and thence rearward, where itmay be joined to a rein 14, which extends to the vehicle, so as to beoperated by the person therein. It will be understood that one of thesedevices is provided for each eye of the horse, and, if desired, the twocords or chains 11 may be joined to a singlerein 14, so as to operatethe two blinkers simultaneonsly.

The shade 7 has a shank-like portion 7, which is arranged to cover thelower portion of the bod y-plate 5 and which is formed with flangesextending around a flange 15, fastened rigidly on the body-plate 5. Theshade is mounted on the flanges 15 of the body-plate Serial No. 14,268.KNO model.)

5 by means of lugs 16, (see Figs. 2 and 8,) which carry a pivot-pin 17,and a spring 1S encircles the pivotpin and bears against a part of thefiange 15 and against the shade 7, so as to normally throw the shadeinto the position shown by full lines in Fig. 3, in which position itwill act simply as the usual blind or shade for horses, and thereforeWill not completely cover the eye. A stub shaft or pin 1S) is mountedrigidly on the body-plate 5, within the 'flange 15, and carries looselya wheel 20, which has a spring-pressed pawl 21, Working with aratchet-Wheel 22, fast on the shaft 19. The wheel has two cams 23, eachof which covers approximately one-half of the circle of the Wheel, thecams being arranged concentrically to the axis thereof. On the cams 23 aprojection 24 of the shade 7 rides, so that as the wheel 20 turns tomove the cams 23 under this projection 24 the shade is thrown from itsnormal position (see full lines in Fig. 3) to its abnormal or act-iveposition. (See dotted lines in Fig. Mounted to rock on the shaft 19 isan arm 25, beneath which bears a collar 26 and between which and thewhe-el 20 bears a second collar 27. By this arrangement the arm isproperly spaced from the body-plate 5 and from the wheel 20, so that itsfree movement is permitted. A stop 28 is fixed on the bodyplate 5,within the flange 15, and is engaged by the arm 25 to limit its movementin one direction. (See Fig. 2.) A. spring-pressed pawl 29 is carried bythe end of the arm 25 opposite the stop 28, and this pawl engages withteeth 30, formed on the periphery of the wheel 20. These teeth 30 areaccording to the construction here shown four in number, so that eachmovement of the arm 25 throws the wheel 20 for one-quarter of arevolution. The rod 9 is pivot-ally connected with the arm 25, so thatthe movement of the rod will be imparted to the arm, it being understoodthat the rod is mounted in the tube 8 with sufiicient freedom ofmovement to compensate for the movement of the arm 25, which is around aconstant axis, as will be understood. The spring 10 on the rod 9 holdsthe arm 25 normally in the position shown in Fig. 2. Now by pulling onthe rein 14 and cord 11 therod 9 will be moved up, and a quarter of arevolution will be imparted to the wheel IOO 20, so that one of the cams23 will act on the shade 7 to throw it from one position to another. Thewheel 20 turns continuously, and the projection 24 first rides on andthen rides olf of one of the eams. Therefore to throw the shades inagainst the head of a horse to completely cover its eyes but onemovement of the rod 9 is necessary, and then to uncover' the eyes of ahorse a second movement is necessary. By these means the shades may bekept completely under the control of the driver, and by placing themover the horses eyes to cover the same the horse will be instant-lystopped, as is well known to horsemen.

Having thus described my invention, I claim as new and desire to secureby Letters Patentl. A horse-blinker, comprising a body, a shade movablymounted thereon to cover or uncover the eye of a horse, a cam mounted onthe body to actuate the shade, and means for operating the cam.

2. A horse-blinker, comprising a body, a shade movably mounted thereon,a earn actuating the shade to @over or uncover the eye of a horse, amoving arm having a pawl for driving the cam, and means for driving thearm.

3. A horse-blinker having a body, a shade movably mounted thereon, arotating cam for actuating the shade to cover or uncover the eye of ahorse, an arm mounted to turn upon the axis of the cam, a pawl carriedby the arm and acting upon the cam to drive the same, and means fordriving the arm. 4. A horse-blinker, comprising a body, apivotally-mounted shade movable on its pivot to Cover or uncover the eyeof a horse, and a wheel with two cams thereon, such cams being each of alength equal approximately to onefhalf the circumference of the Wheel,the cams acting upon the shade to actuate the same in the mannerdescribed.

In testimony whereof I have signed my name to this specilication in thepresence of two subscribing witnesses.

FRANK MACK.
